Title: Electronic flash apparatus
IPC: H05B41/32
Filed: 1973-12-28
Abstract: 1407310 Electronic flash apparatus FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 28 Dec 1973 [7 Feb 1973] 60074/73 Heading G2A In electronic photo-flash apparatus in which the duration of the flash is automatically regulated by the light reflected from the subject, the discharge of the flash tube is controlled by a thyristor, and the voltage drop in the flash tube, upon ignition, causes the thyristor to open. As shown, the series-connected flash tube 3 and thyristor 4 are in parallel with a storage capacitor 1 which is charged up to the working voltage by a D.C. converter 2. Two series-connected resistors 7 and 8 are connected across the flash tube, and a shunt resistor 6 is in parallel with the thyristor. The junction of resistors 7 and 8 is connected to the control grid of the thyristor, and a capacitor 9 is in parallel with resistors 6 and 7. A further thyristor 12 is triggered by a photo-electric device 14 which measures the light flux reflected from the subject. The flash tube is ignited by an impulse from an ignition device 10. When the light flux for the correct exposure is perceived by the device 14, an ignition pulse is applied to the thyristor 12, which triggers the thyristor 4 into the blocking state and so interrupts the flash. During this quenching process the capacitor 9 discharges via resistors 6 and 7, which arrangement additionally subjects the control grid of the thyristor 4 to a negative voltage, and so ensures a more reliable blocking action.

Title: Sensing the developing capability of xerographic developer material
IPC: G03G15/08
Filed: 1968-12-31
Abstract: 1,216,690. Developing electrostatic images. RANK XEROX Ltd. Dec.31, 1968 [Jan. 2, 1968(2)], No.61834/68. Heading G2H. The density of electroscopic toner in developer material is sensed by positioning an electrode adjacent the flow of developer material through a sensing chamber 300 while alternating the polarity of the electrode to attract and repel toner to and from the electrode and passing a beam of light through the electrode towards a photo-cell which generates a signal applied through a control circuit to a toner dispenser 10. The toner dispenser 10 has a container 120 provided with a reciprocutory dispensing plate through which a metered quantity of toner can fall to the reservoir portion of the developer housing 20. The plate is reciprocated by an electric motor MOT-1. The chamber 300, Fig. 6 has photo-electric cells P-1 and P-2 positioned to receive light from a lamp LMP-1. Electrically conductive transparent electrodes 350 are positioned in the flow path of developer material from an earthed flow divider 303 to an aperture 304. Each electrode 350 has electrically isolated areas (350(A) and 350(B)) Fig. 8 (not shown) connected to terminals (10, 15) Fig. 4 (not shown) to provide the alternating polarity of these area Fig.5 (not shown). The alternating polarity causes alternate attraction and repulsion of the toner to the electrodes 350 Fig.6. The photo-electric cells P-1 and P-2 are included in a bridge circuit, Fig. 9. A high resistance of P-2 indicates a high toner concentration on the electrode 350. The bridge circuit feeds a fluctuating voltage Fig. 5 (not shown) through line 2, Fig. 9, to control circuit Fig. 4(b) (not shown). Should this voltage be insufficient to produce conduction of transistor (Q19), indicating a low toner concentration, the motor MOT-1, Fig. 2, will be energized to cause toner to be dispersed for a period e.g. 2“ seconds to increase the concentration. A manual override is provided to permit an operator to dispense toner into the developer apparatus for a period e.g. 10 seconds. The density of the image may be varied by a potentiometer R-24 to alter threshold voltage of transistor Q19. Reference has been directed by the Comptroller to Specification 1,135,743.

Abstract: 1293169 Preparing fish NATIONAL SEAPRODUCTS 23 Dec 1969 [30 Oct 1969] 62639/69 Heading A2U [Also in Division B5] Fish or other edible flesh food in a partially frozen state, preferably at 20F., is formed into portions of predetermined size and shape by a moulding process, such that portions are formed which have a smooth contoured outline, i.e. free from sharp comers, as seen in plan. Apparatus for performing the method comprises a vertically reciprocating head 20 carrying a number of dies 21, a fixed platten 12 below the dies, a conveyor belt 28 travelling horizontally over the platten 12, a magazine assembly 24 having a number of magazines 34 each holding a stack of fish portions cut to a rectangular shape as seen, in plan, a horizontally reciprocating feed plate 38 for extracting the bottom fish portion from each stack and feeding it to positioning guides 44 above the conveyor belt 28, and means for driving the conveyor belt intermittently from a common drive arrangement for the head 20 and the feed plate 38, so that, after a number of fish portions have been aligned in the guides 44, they are moved by the belt 28 under the dies 21, which are then in their raised position, and the belt is then arrested while the dies descend and mould the portions to the desired shape, e.g. the shape of a fillet of fish, whereafter the dies are raised and the process repeated. To prevent the moulded fish portions from adhering to the dies when the latter are raised, compressed air is fed from a manifold 88 to the dies to eject the fish portions. Preferably, in addition, a tape 82, Fig. 2, of plastic material is also used, the tape lining the die cavity as the portions are moulded and being stretched taut to eject the portions when the dies are raised. A plunger may alternatively be used to eject the fish portions, and heating means may be used to assist the moulding process. The driving arrangement comprises a reciprocating head 18 operated by a hydraulic ram 46 and connected with the head 20 by vertically sliding rods 16, sprocket wheels 58, 74 carried by the rods 16 for changing the lengths of bights in chains 60, 68 to reciprocate the feed plate 38, and a rack 48 carried by the head 18 for intermittently driving the conveyor belt via a pinion 50, a free-wheel clutch, and sprocket chain 56.

Title: Electronic timer
Inventor: KLASING CHARLES HERMAN
IPC: H03K17/28
Filed: 1969-12-29
Abstract: 1298830 Transistor delay circuits P R MALLORY & CO Inc 29 Dec 1969 63133/69 Heading H3T A timer includes a capacitor 38 which may be charged to a predetermined voltage through a first resistor 39, and a switching circuit 53 which, on attainment of the predetermined voltage, disconnects resistor 39, connects a second resistor 26 into the charging path and energizes an indicator 54. The timer is started by momentarily closing switch 37, rendering transistor 10 conductive. This turns on transistors 19, 20, the collector of the latter being coupled back to the base of transistor 10 to hold it on when switch 37 is released. A second contact on switch 37 ensures that capacitor 38 is completely discharged. Conduction of transistor 10 also turns on transistor 27 to reverse bias diode 29, so that resistor 26 is disconnected from capacitor 38, and on release of switch 37 the capacitor charges through resistor 39. When the voltage across capacitor 38 reaches a predetermined value, transistors 22, 24 are turned on, to reverse bias diode 25, turning off transistors 27, 30. When transistor 30 ceases to conduct, the collector of transistor 31 is no longer clamped to earth, and oscillator 54 commences to oscillate, producing an audible output. At the same time, turning off transistor 27 forward biases diode 29 and reverse biases diode 28 so that capacitor 38 charges through resistor 26 instead of resistor 39, the charging rate being higher. When the voltage across the capacitor reaches a second predetermined value transistor 17 is switched on, turning off transistor 19 and breaking the hold-on circuit for transistor 10. This disconnects the power supply to all the transistors and hence terminates the audible signal. The oscillator 54 comprises a pair of crosscoupled transistors 31, 34, one of the coupling paths including a piezoelectric device 36 which emits sound.
